Weather and climate in Cabo San Lucas (Baja California Sur)

The climate of Cabo San Lucas is tropical desert, with a pleasantly warm winter from December to March, and a hot summer from May to October, within which there is a relatively rainy period from July to September.
The city is located on the southern tip of the California Peninsula, in Los Cabos municipality. We are at the meeting point between the Gulf of California (or Sea of Cortez) and the Pacific Ocean, that is, between two different worlds.
In winter, when cool air arrives from the United States, some days can be a bit cool and windy, with the night temperature dropping to 8/10 °C (46/50 °F), but even in these cases, in the daytime it usually remains above 20 °C (68 °F).
On the hottest days of the year, which can occur from May to October, the temperature generally reaches 38/39 °C (100/102 °F). In summer, the temperature is slightly lower than in the neighboring city of San José del Cabo. During the summer, the humidity gradually increases, and the muggiest month is September. However, even in summer the temperature can drop when the wind blows from the ocean.
From June to November, but with a higher probability from August to October, the Baja California peninsula can be affected by hurricanes of the Pacific Ocean, as happened with Hurricane Odile in September 2014. However, hurricanes are rare in June, the month in which they are most frequent is September, and historically they have never occurred in November.

Best Time

Cabo San Lucas can be visited from mid-November to March, as it is the mildest season. During the day you can enjoy the sun, while in the evening you will need a sweater and a light jacket.
